Research on reactive power voltage control strategy of distribution network based on information sharing technology

Abstract In view of the fact that the traditional voltage control of the distribution network is suitable for local voltage control and affects the economy of the operation of the distribution network, a reactive power voltage control strategy of the distribution network based on information-sharing technology is proposed. First, the overall architecture of voltage control in the distribution network based on information-sharing technology is analyzed, and secondly, an algorithm based on the Jacobian sensitivity matrix is established with the minimum voltage RMS as the control goal. The model is solved, and finally, the effectiveness of the proposed voltage control strategy is verified by combining actual examples. The results show that the proposed voltage control strategy has a better voltage regulation effect and effectively reduces the overall voltage deviation of the distribution network.

Simulation experiments prove that the Internet of Things technology is effective and can effectively support the sharing of urban public sports information.

Perceptions of organizational capacity to promote physical activity in Canada and ParticipACTION's influence five years after its relaunch: a qualitative study.

ParticipACTION is a Canadian physical activity communications and social marketing organization relaunched in 2007. The purpose of this study was to qualitatively investigate organizational capacity for physical activity promotion among Canadian organizations, and the influence of ParticipACTION on capacity five years after relaunch. Using a purposive sampling strategy, semi-structured telephone interviews were conducted with 44 key informants representing national, provincial, and local organizations with a mandate to promote physical activity. Interview data were analyzed using a thematic analytic approach. Organizational capacity in terms of partnerships and collaborations, and the general climate for physical activity promotion have improved since ParticipACTION's relaunch. Although financial resources reduced the ability of organizations to fulfil their mandates, internal factors such as skilled employees and sponsorships, and external factors such as technological improvements in communication and information sharing helped to offset this strain. There were mixed feelings on ParticipACTION's contribution to capacity. While ParticipACTION has brought more attention to inactivity, this was perceived as a complement to work already taking place. While some organizations perceived ParticipACTION's relaunch as competition to funding and access to popular media, others found it as an opportunity to co-brand social marketing campaigns, utilizing ParticipACTION's products and reputation. According to participants, organizational capacity to promote physical activity in Canada has increased since 2007 in subtle but important ways because of a strong climate for physical activity promotion, skilled employees, and information sharing technology. Organizational capacity changes were minimally attributed to ParticipACTION.

Supporting Client and Family Engagement in Care Through the Planning and Implementation of an Online Consumer Health Portal.

Web-based portals and electronic health records are making it easier for clients and families to access health information. This improved transparency and access to information has the potential to promote activation and improve outcomes, but to realize these benefits, the information needs to be valuable, meaningful, and understandable. Engagement of the end users in the planning and implementation will ensure that the product meets the needs of the consumers. The purpose of this case study is to describe the client and family engagement strategies that were employed to support the process of planning and implementing an online consumer health portal at a pediatric rehabilitation hospital to support the successful launch of this new information-sharing technology platform.

Phenotyping: targeting genotype's rich cousin for diagnosis.

There are many current and evolving tools to assist clinicians in their daily work of phenotyping. In medicine, the term 'phenotype' is usually taken to mean some deviation from normal morphology, physiology and behaviour. It is ascertained via history, examination and investigations, and a primary aim is diagnosis. Therefore, doctors are, by necessity, expert 'phenotypers'. There is an inherent and partially realised power in phenotypic information that when harnessed can improve patient care. Furthermore, phenotyping developments are increasingly important in an era of rapid advances in genomic technology. Fortunately, there is an expanding network of phenotyping tools that are poised for clinical translation. These tools will preferentially be implemented to mirror clinical workflows and to integrate with advances in genomic and information-sharing technologies. This will synergise with and augment the clinical acumen of medical practitioners. We outline key enablers of the ascertainment, integration and interrogation of clinical phenotype by using genetic diseases, particularly rare ones, as a theme. Successes from the test bed or rare diseases will support approaches to common disease.

A calibration method of detecting soil water content based on the information-sharing in wireless sensor network

In agricultural production, there is contradiction between the cost and accuracy of detection during the course of acquiring soil water content ( θ) online. This conflict is one of the core issues of automatic water-saving irrigation technology in agriculture. At the same time, capacitive soil moisture sensor (CSMS) has received considerable attention, for it can acquire θ with low cost and high precision, and meet the application requirements of wireless sensor network (WSN). But CSMS is vulnerable to the soil temperature ( T s) and salinity ( S s) in the measurement process. Therefore, this study took EC-5 sensor for example to establish water detection calibration models of soil temperature and salinity for single sensor, using Least Squares Support Vector Machines on MatLAB (LS-SVMlab) as the tool. On this basis, we explored the spatial variability of T s and S s, and then a method, which could be used to calibrate the output signals of sensors in multi-point network, was proposed based on the information-sharing ( T s or S s) technology of WSN. Through laboratory experiment, we effectively reduced the impact of soil temperature and salinity on the single sensor. In example analysis, we investigated the detection precision and costs under different information-sharing radiuses ( r). And the results indicated that the method we proposed based on the information-sharing technology of WSN could successfully calibrate the influence of soil temperature and salinity on sensors in multi-point network, and it was an efficacious approach to determine the balance between the calibration accuracy of moisture sensor and the investment of agricultural production. For example, while the calibration precision of soil temperature and salinity is respectively 1%, the costs can be reduced by 30%.

New Economy, New Recession?

The National Bureau of Economic Research (NBER) confirmed in November 2001 what many had long suspected - that the U.S. economy was in recession and had been since March 2001. Thus ended an economic expansion that had begun in March 1991, the longest in the NBER chronology that dates to the mid-1800s. During this expansion, many economists and policy analysts talked about a Economy characterized by a higher sustained level of productivity growth brought on by new networking information-sharing technologies. What does the New Economy's new recession look like? This article examines the 2001 recession by comparing it with previous recessions and investigating whether an added degree of resilience and flexibility is evident in the economy. The downturn appears to have been relatively mild and to have been tempered by the productive use of information technologies. Paradoxically, the information technology sector itself was hit exceptionally hard.

Empowering children and families with information technology.

Patient empowerment is the enhanced ability of patients to actively understand and influence their health status. Information is the key to patient empowerment. Without information, children and families cannot engage in meaningful discussions or make thoughtful decisions regarding medical care. Information sharing is a model for patient interaction with the health care system that may significantly improve the care of children and families. This article focuses on information technologies that utilize user-centered design principles and interactive capabilities to facilitate information sharing and to empower children and families. Examples include electronic pediatric personal medical records, customized health information systems, and interactive physician offices with electronic mail (e-mail) and telemedicine capabilities. Ideally, these systems would all be integrated. Successful implementation of new technologies will require thoughtful attention and balanced solutions to tensions between information sharing vs security, and curatorship vs censorship. Issues related to access and the digital divide must also be addressed. Acceptance and usability of new technologies is predicated on close collaboration among physicians, researchers in informatics, librarians, educators, and other professionals with expertise in the human-computer interface. Child and family empowerment will be both the driving force and ultimate outcome of information-sharing technologies.
